The risk of skipped steps is just something said back then when first making the modification. Been running for 2+ years that way and never one skipped step related to cooling. Dozens of other users have done the same mod.

Again, please understand, my N1 is my most reliable bulletproof printer. I've printed print objects longer than 24 hours continuous with this mod in place just days after first getting the printer. Here is a short list of projects printed on the N1 and some parts took over 38 hours for a single part. viewtopic.php?f=5&t=814&p=7711&hilit=arm#p7711

Just understand why that is not listing the N1- it's all because the N1 does not use the cable chain wire guide that is on the N2 series.I just showed that you really probably should take the time anyway, inspect the factory flex tube wire guide, I used flex loom and a nylon 1/4 inch water tubing to stiffen the arch and limit bend radius, and use my own method (cable ties) around the motor.
